Have you heard of Manifest Destiny?

Likewise. I thought it would be about some kind of "name a star" service, but now you get not only a star, but all the celestial bodies in orbit, too. The linked article says, "Rooftop Solar Power..." which is much more clear.

Well, it is systems so not one for US but anyone living in US can have their own solar system.
